• HR Coated for UV, Visible, and IR Applications from 250 nm to 10 μm
• Multiple Reflective Magnifications from 2X to 5X
• Monolithic Design for Reduced Thermal Effects and Simplified Alignment
TECHSPEC® Canopus™ Reflective Beam Expanders are ideal for applications requiring broadband or achromatic
beam expansion and a wide variety of light sources. The all-reflective design enables these beam
expanders to be used with a variety of lasers including tunable, ultraviolet, and ultrafast sources, while the
innovative design ensures high precision with minimal wavefront distortion. A variety of integrated design elements,
including reflective flats, threaded holes, and thru-holes, simplify alignment, mounting, and integration
into any laser application. The monolithic design ensures performance and stability independent of changes
in temperature. TECHSPEC® Canopus™ Reflective Beam Expanders are available in 2X, 3X, and 5X magnifications,
along with coating options for the UV, Visible, and IR spectra.

Anamorphic Prism Pairs
• Adjustable and Fixed Magnifications
• Ideal for Reshaping Elliptical Profile Laser Diodes
• Compatible with TECHSPEC® Cage System or Standard Post Optical Mounts
TECHSPEC® Anamorphic Prism Pairs are an economical solution to reshaping elliptical profile laser beams.
These prisms utilize refraction in order to expand a beam in one dimension allowing users to manipulate beam
profiles with minimal transmitted wave front distortion. Mounted versions of fixed and variable magnification,
as well as unmounted versions are available for application flexibility. TECHSPEC® Anamorphic Prism Pairs
are designed to be integrated with standard Edmund Optics mechanics such as the TECHSPEC® Cage System
Component Kit and TECHSPEC® Stainless Steel Mounting Posts, providing laser integrators with more options
for circularizing laser beam profiles.
